Estimated calculations and should only be taken as suggestions.

1988 GMC G1500 Rally STX tire load inflation table provides tire pressure psi values corresponding to tire's weight load in pounds (lbs).

If your vehicle is carrying extra load, increase your tire pressure accordingly. Never overinflate tires above maximum tire pressure indicated on tire sidewall.

If you replace your original equipment tires with plus size tires, or tires with different tire size, make sure to use tire load inflation chart to find corresponding tire pressure for your new tires.
